Nokia board chairman Risto Siilasmaa went on a Finnish television show, and stated that while he is confident in Windows Phone 8, the company does have a back-up plan if it doesn't work out. Speculation aplenty - what is this backup plan? The answer's pretty easy, if you ask me.

If they license and release an Android phone it could invalidate future lawsuits against Android using Nokia patents.

It is the same as SCO releasing a Linux distro and later deciding to sue Linux after willingly releasing the same code under GPL.

It doesn't apply to hardware patents but it would still make their patent portfolio worth less since the main reason someone would want to buy it would likely be to sue Android phones out of existence.
